They were both factors. In the long-run, the Soviet Union's massive and rapid mobilization was the key to its ultimate victory in the war, as Germany lacked the manpower to match it.ljadw wrote: ↑15 Aug 2019, 07:08This is not correct :the escape of portions of the Red Army to the east did not influence the outcome of Barbarossa .What decided the outcome of Barbarossa was the ability of the Soviet regime to mobilize very quickly its reserves and to send them to the front : between June 22 and June 30 5,3 million men were mobilised .Without this, the Soviet regime would collaps .Besides, the situation of AGC was not better than the situation in the north or the south of the front .HistoryGeek2019 wrote: ↑14 Aug 2019, 22:24I believe this ATL helps overall with Germany's logistics in Russia. German planners correctly identified that they could adequately supply their forces in western Russia - basically west of the Dnieper-Dvina line. Hence, it made sense for Germany to seek to destroy the entire Red Army west of this line, because that is where Germany could sustain adequate logistics. When sizeable portions of the Red Army escaped to the east (basically everywhere except AGC), this led to the enormous strain on German logistics where there weren't nearly enough rail lines to supply their armies in the east.
Thus, anything that would help encircle more Soviet armies in the early phases of Barbarossa, as in this ATL, would help Germany's overall logistical situation in the east.
To encircle more Soviet armies west of the DD line would not help Germany .
Nevertheless, the successful withdrawal of Soviet troops in all fronts other than Belarus bought the Soviets precious time to deploy their reserves. Had Southwestern Front been encircled per this ATL, the Soviets would have been thinly stretched in July and August.
